PURPOSE The aim of this study was to compare a negative pressure drain with a natural drain in order to determine whether a negative pressure drainage tube causes an increase in the drainage volume. MATERIALS AND METHODS Sixty-two patients who underwent total thyroidectomy for papillary thyroid carcinoma (PTC) were enrolled in the study between March 2010 and August 2010 at Gyeongsang Nationa...

In this paper, we proposed a 2-D analytical model for electrical characteristics such as surface potential, electric field and drain current of Silicon-on-Insulator Tunnel Field Effect Transistor (SOI TFETs) with a SiO2/High-k stacked gate-oxide structure. By using superposition principle with suitable boundary conditions, the Poisson’s equation has been solved to model the channel r...

OBJECTIVE To perform an unbiased assessment of first postoperative day (POD 1) drain amylase level and pancreatic fistula (PF) after pancreaticoduodenectomy (PD). BACKGROUND Recent evidence demonstrated that drain abandonment in PD is unsafe. Early drain amylase levels have been proposed as predictors of PF after PD, allowing for selection of patients for early drain removal. METHODS Daily ...

Most research on the phenomenon of "brain drain" (one-way flow of highly skilled/educated individuals) has focused on movement between the least developed and most highly developed countries. Therefore, the significance of patterns of migration to middle-income countries such as those in Latin America is less clear. The aim of this study was to outline key features of international health worke...

Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence. This study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis. A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital, Abha, Saudi Arabia, was conducted from April 2010 t...

This research was initiated with the objective of investigating the potential of constructed wetlands covered by duckweeds and connected to the branches of Bahr Hadous drain on its salinity, and subsequently, its discharge into El-Salam canal. Primarily, literature was reviewed. Data was assembled and analysed. The water quality model QUAL2K was used in this investigation. Moreover, electrical ...

The 'beneficial brain drain' hypothesis suggests that skilled migration can be good for a sending country because the incentives it creates for obtaining training increase that country's net supply of skilled labour. Necessary conditions for this hypothesis to work are that the possibility of migration significantly affects decisions to take medical training and that migrants are not strongly s...

Abshct This paper describes a new measurement technique, the forward gated-diode current characterized at low drain voltages to be applied in MOSFET’s for investigating hot-carrier stress-induced defects at high spatial resolution. The generatiodrecombination current in the drain-to-substrate diode as a function of gate voltage, combined with two-dimensional numerical simulation, provides a sen...

It cannot be ignored that Iran had an impressive history in science over the very ancient years; through significant number of unique inventions, ideas, and discoveries brought by Iranian scientists such as Farabi, Toosi, Razes, Avicenna, Hesabi, and many others. During centuries due to political, cultural circumstances and war, Iran's activities in all aspects of science and technology (S & T)...
